Hello everybody,

how can I retrieve the activity from a task?
I tried this way, but the activity of this execution is null, although the activityId has the expected value.

        Execution ex = processEngine.getRuntimeService()
            .createExecutionQuery()
            .executionId(task.getExecutionId())
            .singleResult();
        PvmActivity activity = ((ExecutionEntity) ex).getActivity(); // is null
        String actId = ((ExecutionEntity) ex).getActivityId(); // is not null
‍‍‍‍‍‍‍‍

The same code works with the process instance, but what I need is the currently active activity after branching with an exclusive gateway.
Is there an other way of getting the activity?

Best regards
Frauke

Hi,

seems like I found out by myself:
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Execution ex = m_processEngine.getRuntimeService()<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .createExecutionQuery()<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .executionId(task.getExecutionId())<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .singleResult();<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String actId = ((ExecutionEntity) ex).getActivityId();<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ProcessDefinitionImpl p = ((ExecutionEntity) m_processInstance)<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .getActivity()<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .getProcessDefinition();<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PvmActivity activity = p.findActivity(actId);<br>Ok, it may not look extremly elegant, but it works.
Still the other way would be easier…
